Our design team watched football players in action on the pitch to develop this Hybrid ball.
This ball is a hybrid due to a concept that combines the comfort of machine sewing with the durability of hand sewing.
We also used a bladder with winded thread (2 km of threads are wrapped around the bladder) to ensure durable inflation and better sphericity.

Weight

Between 370 and 390 g (Size 4)

Circumference

Between 63.5 and 64.5 g (Size 4)

Sphericity

Average measured variation: Maximum of 1.5%.

Maximum pressure loss

20% in 72 hours

Water absorption

15% (test carried out in 2 cm of water with 250 compressions, and constant rotation of the ball)

Bounce

Between 135 and 155cm with a maximum difference of 10cm between the ball's highest and lowest bounce. Each ball is dropped 10 times on a steel plate from a height of 2 metres.

Shape and pressure retention

Resists up to 2500 shots against an inclined concrete surface at 50km/h at a distance of 2.5m. Maximum 1.5cm increase in circumference, maximum 1.5 % variation in sphericity and maximum 0.1 bar change in pressure.
